Congrats on getting this far, and good luck on the interview!
Let me add one thing you might not be prepared for: stamina.
I once had a job interview (series of interviews with various personnel, actually) that lasted on the order of six hours. I was doing really well for about the first four hours. Then I just ran out of steam. Someone else got the offer. I think if I'd been better prepared for something that was going to last that long, I might have been less keyed up first thing in the morning, better able to pace myself. Maybe.![]()
